  • Fuse-protected electronic photodiode array
    Patent number: 10177181
    Abstract: There is provided a photodiode array including a semiconducting substrate and a plurality of photodiodes that are disposed at a surface of the substrate. Each photodiode is laterally spaced apart from neighboring photodiodes by a lateral substrate surface region. An optical interface surface of the substrate is arranged for accepting external input radiation. A plurality of electrically conducting fuses are disposed on the substrate surface. Each fuse is connected to a photodiode in the plurality of photodiodes. Each fuse is disposed at a lateral substrate surface region that is spaced apart from neighboring photodiodes in the plurality of photodiodes.
    Type: Grant

  • Photodiode placement for cross talk suppression
    Patent number: 9911774
    Abstract: There is provided a photodiode array. The photodiode array includes a substrate that has an optical interface surface arranged for accepting external input radiation into the substrate. A plurality of photodiodes are disposed at a substrate surface opposite the optical interface surface of the substrate. Each photodiode in the plurality of photodiodes includes a photodiode material that generates light into the substrate as a result of external input radiation absorption by the photodiode. There is aperiodic photodiode placement along at least one direction of the array.
